The communication unit 12 includes a transmitting/receiving antenna 121 and a radio circuit 122. The transmitting/receiving antenna 121 is built in the body housing 11 at a side where the display unit 14 is provided. The radio circuit 122 modulates sound information, IDs, web page data browsing request information and the like processed by the control unit 17 and transmits the modulated information to a base station that is not illustrated through the transmitting/receiving antenna 121 so as to perform wireless communication utilizing radio waves. The radio circuit 122 also demodulates various information such as page data and sound information transmitted wirelessly from a base station and received by the transmitting/receiving antenna 121, and outputs the demodulated information to the control unit 17.
The sound processing unit 13 includes a sound processing circuit 131 to which a microphone 132 that is an example of an input unit for performing voice input and a speaker 133 for performing voice output are connected for a call function. The sound processing circuit 131 performs predetermined processing on a sound input from the microphone 132 and supplies the processed sound to the control unit 17. The sound processing circuit 131 has a function of a recognition unit that recognizes voice input from the microphone 132. The sound processing circuit 131 also performs predetermined processing on sound information supplied from the control unit 17 and outputs the processed information through the speaker 133.
As illustrated in FIG. 1B, the microphone 132 is positioned below the operating unit 15 and the speaker 133 is positioned above the display unit 14 of the body housing 11.
The display unit 14 includes a display device such as a liquid crystal display (LCD) arranged at an upper part of the body housing 11 as illustrated in FIG. 1B, and displays a telephone number input for the call function, memos such as various messages and text data, etc. Part of the display unit 14 corresponding to one line at the top is used as a guide display line for displaying a mode type, a radio field strength, a remaining battery level and the like.
In particular, the display unit 14 according to the present embodiment can display a plurality of windows called attached memos (an example of objects operated on the screen) having predetermined sizes on the idle screen (standby display) over background display of the idle screen under control by the control unit 17. The idle screen refers to a screen when the mobile phone is switched on and not during a call. The idle screen may also be called a standard screen, an initial screen, a desktop screen, a home screen, or wallpaper, for example.
As illustrated in FIG. 1B, the operating unit 15 is arranged at a lower part of the body housing 11 and includes an end (clearing)/power key 15a, a start (calling) key 15b, a plurality of numerical keys 15c associated with numbers and the like, up, down, left and right keys 15d, a center key 15e, and the like.
The memory 16 includes an EEPROM, for example, and stores therein control programs for calls and/or transmission/reception of mail messages, an Internet browser, message data, an address book in which names and phone numbers are registered, etc. The memory 16 also stores therein application programs to be executed by the control unit 17.
The memory 16 further stores therein attached memo data (an example of object data) corresponding to respective attached memos. The attached memo data are composed of data registered as attached memos each of which being associated with displayed text data to be displayed in a window, symbol data, window display position data in addition to link data for the data.
The displayed text data are text data determined according to predetermined priority among text data included in various data or part thereof stored in the memory 16 and selected by a user through the operating unit 15. An upper limit is set to the amount of text data displayed in windows displayed on the display unit 14. Since the upper limit is eight characters in the present embodiment, top eight characters of the determined text data become the displayed text data.
The symbol data is used for identifying a symbol displayed in addition to an attached memo when the attached memo is displayed on the display unit 14 so that the user can easily identify the attribute of the memo. The symbol data are associated with a symbol such as image data and an icon that is stored separately from the symbol data.
The control unit 17 is mainly constituted by a microcomputer and performs the integral control of the mobile phone 1. For example, the control unit 17 performs control on wireless transmission/reception of various information by the communication unit 12, processing of sound information for the sound processing unit 13, control on display of information to the display unit 14, processing according input information of the operating unit 15, and access control to the memory 16 according to the processing.
The control unit 17 has functions of a display control unit that controls display of attached memos attached on the idle screen. In the present embodiment, the control unit 17 performs display control of attached memos according to the tilt of the mobile phone body (details of the control will be described later).
The movable mechanism 18 horizontally turnably supports a portion (at a side including the display unit 14) of the body housing 11 and another portion (at a side including the operating unit 15) of the body housing 11. Accordingly, the side of the display unit of the body housing 11 can be horizontally turned in one direction so that the mobile phone can become the open state as in FIG. 1B from the closed state as in FIG. 1A, for example.
The acceleration sensor (detecting unit) 19 is for detecting tilting of the mobile phone body that is the device body. The mobile phone 1 may include another sensor such as a gyro sensor as the detection unit.
==Display Control of Attached Memos According to Tilting of Mobile Phone Body==
As described above, a plurality of attached memos are attached on the idle screen. Since the display area of the idle screen of the mobile phone 1 is limited (small), however, only attached memos corresponding to some of attached memo data among registered attached memo data can be display on the idle screen when the number of memo data (memo information pieces) registered in the memory 16 is large. Accordingly, in the related art, a registration screen of attached memos (a screen different from the idle screen) needs to be displayed so as to check attached memos other than some attached memos mentioned above.
The mobile phone 1 of the present embodiment, therefore, performs display control of attached memos as will be described below so that the user can easily recognize attached memos that are registered in the memory 16 but not displayed on the idle screen. FIG. 3 is a flowchart for explaining display control of attached memos according to tilting of the mobile phone body. FIG. 4 is a state transition diagram of the display unit 14.
The display control illustrated in FIG. 3 starts from display of an idle screen on the display unit 14 by the control unit 17 (Step S2). In the present embodiment, it is assumed that a plurality of (six) attached memos M1 to M6 are displayed such that they are vertically arranged and attached to (overlaid on) the idle screen as illustrated in (a) of FIG. 4. In the present embodiment, it is assumed that up to six attached memos can be displayed at a time on the idle screen. The arrangement order of the attached memos M1 to M6 is stored in the memory 16 in advance.
Then, the control unit 17 detects tilting of the mobile phone body (Step S4). Specifically, the control unit 17 detects whether or not the mobile phone body is tilted for a predetermined time by means of the acceleration sensor 19. When tilting of the mobile phone body is detected (Step S4: Yes), the control unit 17 obtains the number of attached memo data registered in the memory 16 (hereinafter may also be referred to as the number of registered memos) (Step S6).
Subsequently, the control unit 17 determines whether the number of registered memos registered in the memory 16 is larger than the number of attached memos that can be displayed at a time on the idle screen (hereinafter may also be referred to as the number of displayed memos) (Step S8). When the number of registered memos is not larger than the number of displayed memos (Step S8: No), the control unit 17 maintains the state of the idle screen illustrated in (a) of FIG. 4, that is, does not scroll the attached memos on the idle screen (Step S22). It is thus possible to prevent unnecessary scrolling.
On the other hand, when the number of registered memos is larger than the number of displayed memos (Step S8: Yes), the control unit 17 scrolls attached memos corresponding to attached memo data registered in the memory 16 by sequentially moving the attached memos on the idle screen as will be described below. In the present embodiment, the scrolling of the attached memos will be described assuming that the number of registered memos registered in the memory 16 is eight (attached memos M1 to M8). Accordingly, the objects to be scrolled are not the attached memos M1 to M6 illustrated in (a) of FIG. 4 but the attached memos M1 to M8 corresponding to the attached memo data stored in the memory 16.
First of all, the control unit 17 sets colors with different tones from one another to the attached memos M1 to M8 (Step S10). The tone of colors becomes darker in the order of the attached memos M1, M2, M3 . . . . In other words, the tone of the colors gradually changes in units of memos. As a result of setting colors with different tones to the memos, the user can recognize the progress of scrolling when the attached memos are scrolled, for example.
Subsequently, the control unit 17 moves the attached memos M1 to M8 with colors in the direction of an arrow A illustrated in (b) of FIG. 4 to scroll the attached memos M1 to M8 (Step S12). The arrow A is illustrated for explanation but the arrow A is not actually displayed on the display unit 14. As a result, the attached memos M7 and M8 that are not displayed in the state of (a) of FIG. 4 are displayed in a scrolling manner as illustrated in (c) of FIG. 4. The user can thus recognize the attached memos M7 and M8 that are registered in the memory 16 but are not attached to the idle screen. As illustrated in (c) of FIG. 4, attached memos are sequentially deleted from an end (a first end) of the screen as a result of scrolling.
The control unit 17 determines the display priority of the attached memos M1 to M8 while the attached memos M1 to M8 are scrolled (Step S14). For example, the control unit 17 sets higher display priority to attached memos that are more frequently selected (memos with larger number of clicks). Alternatively, the control unit 17 may set higher display priority to attached memos in which time nearer to the current time is described. Still alternatively, higher display priority may be set to attached memos relating to an application executed immediately before detection of tilting, for example. Information such as selection frequency is stored in the memory 16.
Subsequently, the control unit 17 determines whether or not the order of arrangement according to display priority of the attached memos determined at Step S14 is coincident with the order of arrangement of the attached memos illustrated in (a) of FIG. 4 (Step S16). When it is determined that the orders of arrangement are coincident (Step S16: Yes), the control unit 17 moves the attached memos M1 to M6 to be displayed in the arrangement as illustrated in (a) of FIG. 4 (Step S24).
When it is determined that the orders of arrangement are not coincident at Step S16 (No), the control unit 17 arranges the attached memos M1 to M8 in an arrangement in the order according to the priority to be displayed. Specifically, it is assumed that the priority of the attached memos M2, M3 and M4 is determined to be high, the priority of the attached memos M1, M5 and M6 is determined to be medium, and the priority of the attached memos M7 and M8 is determined to be low.
Then, the control unit 17 moves only the attached memos M1 to M6 with higher priority among the attached memos M1 to M8 upward from a lower portion of the screen (an end opposite to the first end) after scrolling as illustrated in (d) of FIG. 4 (Step S18). Thus, the attached memos that have once been deleted from the screen are displayed again.
Subsequently, the control unit 17 displays the attached memos M1 to M6 in an arrangement in descending order of the priority as illustrated in (e) of FIG. 4 (Step S20). As a result, the order of arrangement of the attached memos M1 to M6 is changed according to the priority between before and after scrolling. Since the attached memos M1 to M6 are arranged in descending order of the priority, the user can easily recognize a desired attached memo (an attached memo with higher priority).
In the above description, the priority of the attached memos M7 and M8 are low; however, when the priority of the attached memo M7 is high, for example, the attached memo M7 will be displayed on the idle screen instead of any one of the attached memos M1 to M6 after scrolling. As a result, the attached memo M7 that has a high priority but is not attached to the idle screen by the user will be automatically attached to the display screen after scrolling. The user can thus skip such an operation of displaying a registration screen for checking the attached memo M7 with high priority as in the related art.
In the above description, an embodiment in which the attached memos M1 to M8 are all once deleted from the screen and then displayed again on the idle screen during scrolling is presented; however, embodiments are not limited thereto. For example, when the attached memos M7 and M8 are positioned at an upper portion of the screen as illustrated in (c) of FIG. 4, the control unit 17 may display the attached memos once deleted on a lower portion of the screen. In such a case, the scrolling time for the attached memos is reduced.
Other Embodiments
A mobile phone as an embodiment has been described. The above embodiment is provided to facilitate understanding of the present invention but not to lead to limited interpretation of the present invention. Needless to say, the present invention can be modified and improved without departing from the scope thereof, and equivalents thereof are included in the present invention. In particular, embodiments described below are also included in the present embodiment.
While a mobile phone 1 is described as the mobile electronic device in the embodiment described above, the mobile electronic device is not limited to mobile phones but may be PHSs (personal handy phone systems), PDAs (personal digital assistants), portable navigation devices, electronic dictionary devices, and laptop computers, for example.
While the mobile phone 1 has a structure that can be horizontally turned as illustrated in FIGS. 1A and 1B in the embodiment described above, the structure is not limited thereto. For example, the mobile phone 1 may be a folding type mobile phone, a sliding type mobile phone, or a straight type (slate type) mobile phone formed of one housing.
While the scrolling direction of the attached memos is the direction of the arrow A illustrated in (b) of FIG. 4 in the embodiment described above, the scrolling direction is not limited thereto. For example, the attached memos may be scrolled either in the direction of the arrow A illustrated in FIG. 4 and in the direction opposite thereto depending on the tilting direction of the mobile phone body.
While the attached memos M1 to M8 are scrolled after tilting of the mobile phone 1 is detected in a state in which the idle screen is displayed in the embodiment described above, the control of scrolling is not limited thereto. For example, the attached memos may be scrolled when one application being executed is terminated (or suspended) and the display is accordingly switched from the screen for the application to the idle screen.
While the objects to be scrolled are the attached memos in the embodiment described above, the objects to be scrolled are not limited to attached memos. For example, the objects to be scrolled may be icons, images or incoming and outgoing call history instead of attached memos.
While the attached memos are scrolled in the direction in which the mobile phone is tilted detected by the acceleration sensor 19 in the embodiment described above, the control of scrolling is not limited thereto. For example, the attached memos may be scrolled when it is detected by the acceleration sensor 19 that the mobile phone body is shaken by the user.
In an embodiment in which the objects are icons, an application program associated with an icon may be executed by the control unit 17 when the icon is selected via the operating unit 15. In this embodiment, the control unit 17 may set the display priority higher to objects more frequently selected. In this embodiment, the control unit 17 may set the display priority higher to objects with later selected time. In this embodiment, in a case where execution of an application program associated with an icon selected on a standard screen on which the icons are arranged is terminated and the display screen is thus switched from a screen other than the standard screen to the standard screen, icons may be scrolled on the standard screen.
